Nectarine tree named ‘CAKEDIVA’

ABSTRACT

A new and distinct variety of white flat nectarine tree denominated ‘CAKEDIVA’ has fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet white flesh, sometimes with a red pigmentation in a star shape around the stone cavity and into the stone cavity, and an attractive luminous skin with a high to very high percentage of luminous purple red blush on skin surface, on a pink red or washed background. The new variety has also a late maturity time.

Botanical classification: Prunus persica (L.) Batsch.

Variety denomination: ‘CAKEDIVA’.

This application claims priority of Community plant variety right No. 2018/3133 filed on Nov. 29, 2018 (Nov. 29, 2018) which is hereby incorporated by reference in its entirety.

The new variety named ‘CAKEDIVA’ is also known as 26.20.64.14 NBPL or ASF17204. Indeed, before giving a name to a new and distinct variety of fruit tree, a provisional reference is assigned, considering the references of a tree in orchard. This provisional reference is constituted firstly with the number of the parcel on which the tree has grown, then the number of the line, the tree number and finally the year of selection. Then before being named ‘CAKEDIVA’, the provisional reference of this white flat nectarine tree variety was 26.20.64.14 NBPL, corresponding to the tree 64 located in line 20 of the parcel 26 and selected during the year 2014. The letters “NBPL” are related to the first letters of the type of tree in French (NBPL for “Nectarine Blanche PLate”, that means “white flat nectarine”). Once the hybrid selected, the breeder assigned a clone reference that begins with the letters “ASF” followed by the year of selection and a number corresponding to the maturity order. The final name is only assigned once the application has been filed and the name approved after its publication in the official bulletin. For the variety ‘CAKEDIVA’, the clone reference was ‘ASF17204’.

BACKGROUND OF THE NEW VARIETY

The present invention relates to a new and distinct variety of white flat nectarine tree, Prunus persica (L.) Batsch, which has been given the variety denomination ‘CAKEDIVA’.

This new tree produces fruits with a long shelf life without alteration both on the tree after growth completion and after harvesting, very good eating quality, semi-clingstone white flesh fruits, slightly greenish, for fresh market in September in the Pyrénées-Orientales department, France.

ORIGIN OF THE VARIETY

The ‘CAKEDIVA’ white flat nectarine tree originated from a cultivated area of the south of France, in the Pyrénées-Orientales department, where it was tested.

This place is under a Mediterranean climate (a temperate area), on the Mediterranean coastline. Winters are gentle and summers warm and dry. The amount of days with temperatures below 7° Celsius can vary between 600 and 1200 hours per year. The place is sunny, with 2400 to 2800 hours of sunny days per year on average. The prevailing wind is called ‘Tramontane’: it dries the air, clears the sky from clouds, but its intensity can be strong and affect the harvest, fruit quantity and/or quality. Marine moisture does not affect the place. Precipitations are irregular through the year and from one year to another. The amount of rainy days does not exceed 80 days per year and are mostly found in Spring and Autumn. In May and October, very intense precipitations occasionally happen. Summer is dry with a few thunderstorms.

The ‘CAKEDIVA’ variety results from a pollinated cross between a white nectarine tree named ‘NECTARPERF’ (U.S. Plant Pat. No. 23,357) which was used as a seed parent, or female parent, and the ‘CAKEDELICE’ (U.S. Plant Pat. No. 25,632) white flat nectarine tree which was used as the pollen parent, or male parent.

The ‘CAKEDIVA’ variety was obtained by hybridizing and propagated by grafting on a ‘INRA GF677’ (non-patented) rootstock trees. It has been determined to have unique tree and fruit characteristics making it worthy for commercial fresh fruit production. There are no known effects of the standard rootstock trees set forth above on the scion cultivar. Asexually propagated plants remained true to the original tree and all characteristics of the tree and the fruit were transmitted. The plant was reproduced asexually by us in Les Régalines, Route d'Alenya, La Prade de Mousseillous, 66200 ELNE, Pyrénées-Orientales, France. More particularly, the plant was reproduced by grafting.

SUMMARY OF THE VARIETY

The new and distinct variety ‘CAKEDIVA’ white flat nectarine tree blooms mid-February or at the end of February near Elne in the Pyrénées-Orientales department, France. The blooming period is considered medium. However, it was observed that its late date of blooming seems to be highly dependant on climatic conditions.

The first fruit of ‘CAKEDIVA’ ripens late or very late in the season, namely at the end of August. More particularly, it usually ripens between August 28^(th) and September 26^(th). However, it was observed that its date of maturity seems to be highly dependant on climatic conditions.

DETAILED BOTANICAL DESCRIPTION

The tree, flowers, and fruit may vary in slight detail due to variations in soil type, cultural practices, and climatic condition. The potential for commercial production of fresh fruits by ‘CAKEDIVA’ is high, due to fruit very long shelf life without alteration after harvesting.

Trees are medium vigorous and large stature half-standing in a semi-flared to semi-upright out aspect. The anthocyanic coloration of flowering shoot is present excluding brushwood side away from sun. The time of beginning of flowering is considered medium; flowering begins mid-February or at the end of February. The type of flower is showy (rosette) with medium to large petal size. Petals are pink to medium pink. Leaf glands are present and reniform. The fruit flesh is white to slightly cream, sometimes with a slightly red pigmentation into the stone cavity and in a star-shape around the stone cavity. The fruit skin is medium thick, with a luminous purple red blush on a pink red to washed red background. The stone is semi-clingstone and its size is small. Fruit taste is semi-sweet, aromatic and with a high level of sugars.

Compared to ‘CAKESEPTEMBER’ white flat nectarine variety (not patented), the fruits of ‘CAKEDIVA’ ripen approximately eight days earlier. The fruits of the new variety ‘CAKEDIVA’ are round and symmetrical, whereas the fruits of ‘CAKESEPTEMBER’ are considered more or less round. The fruit skin of the new variety ‘CAKEDIVA’ is colored with a luminous purple red blush covering at least 85% of the skin surface and sometimes 100%, on pink red background. In comparison, the fruits of ‘CAKESEPTEMBER’ are less colored. The red blush covers 80 to 90% of the surface on a cream pink background. The closing of the pistil cavity is better in the ‘CAKEDIVA’ fruits, in comparison with the fruits of the ‘CAKESEPTEMBER’ variety. Finally, the fruits of the new variety ‘CAKEDIVA’ have a long shelf life before and after the harvest. In comparison, the fruits of ‘CAKESEPTEMBER’ have a medium shelf life.

Compared to its seed parent, which is a round white nectarine tree named ‘NECTARPERF’ (U.S. Plant Pat. No. 23,357), the new variety ‘CAKEDIVA’ is a white flat nectarine tree. The fruits of the new variety ‘CAKEDIVA’ ripen approximately as the same period as the fruits of ‘NECTARPERF’.

Compared to its pollen parent, the white flat nectarine ‘CAKEDELICE’ (U.S. Plant Pat. No. 25,632), the fruits of the new variety ‘CAKEDIVA’ ripen generally one month later.

DETAILED DESCRIPTION

Referring more specifically to the pomological details of this new and distinct variety of white flat nectarine tree, the following was observed on trees in their third growing season (second year of production) for trees, leaves and fruits and on trees in their second growing season (first year of production) for the flowers under the ecological conditions prevailing at the orchards located near the town of Elne, Pyrénées-Orienteles departement, France. All observations have been done on rootstock cultivars. Used rootstocks were ‘INRA GF677’ (non-patented) trees. All major color code designations are by reference to The R.H.S. Colour Chart (Fourth Edition) provided by The Royal Horticultural Society of Great Britain.

-   Tree:     -   -   Size.—         -   Generally.—Considered large. The tree size the first year             was approximately 200 to 280 cm. The tree was pruned during             each following dormant season to a height of approximately             250 cm. Current season shoots growth could reach 80 cm. The             tree size from the second year (second and next years)             reached a final height of 330 cm including current season             shoots length. The tree size is consistently reduced to 250             cm the next years.         -   Spread.—Approximately 100 cm with a cylindrical shape. The             whole orchard was oriented to a central leader organization,             with tree lines spaced of 4.0 meters and trees spaced of 1.0             meter in a same tree line. As a result, tree spread was             about 100 cm and the orchard contained 2500 trees by             hectare.         -   Vigor.—Considered medium.         -   Productivity.—Very productive. Fruit set is spaced by             thinning to develop the remaining fruit into the desired             market sized fruit. The number of the fruit set varies with             the prevailing climatic conditions and cultural practices             employed during the bloom period and is therefore not             distinctive of the present variety. A reduce vegetation,             obtained with pruning or green pruning, approximately 1             month or 1-month ½ before harvesting flat fruits,             significantly promotes fruit qualities, especially growth,             color and firmness. Moreover, contamination risks due to             Monilia or rot are significantly reduced. ‘CAKEDIVA’ variety             is not much sensitive to cracking of pistil cavity, to cork             formation into peduncle cavity or to Monilia.         -   Bearer.—Very regular. The fruit distribution is considered             homogenous on mixed branches and spurs having more than 1             year. Thinning of 2 fruits out of 3 was necessary for the             tree valorisation. Thinning was necessary every year during             the years of observation.         -   Form.—The ‘CAKEDIVA’ variety has naturally a semi-flared to             semi-upright shape.         -   Density.—Considered dense.         -   Hardiness.—The present tree was grown and evaluated in             France. The variety appears to be hardy under the central             Pyrénées-Orientales departement typical climatic conditions.             Experimentations on different sites with winter chilling             requirement comprised between 350 hours and 1200 hours             showed a good behaviour of the tree in all cases.             Traditionally, flat fruits are more sensitive to critical             low temperatures and to climatic variations, because of the             flower morphology in which the ovule is less protected than             in the classical round fruits. Thus, areas not much exposed             to frost are recommended for trees growth. However,             ‘CAKEDIVA’ trees seem to be very resistant to critical             frosty weather. Experimentations on the same orchard in             Elne, Pyrénées-Orientales department, with winter chilling             requirement below 7.2° C. comprised between 350 hours and             1200 hours according to the specificities of the year, 1031             hours in 2012-2013, 777 hours in 2013-2014, 893 hours in             2014-2015, 718 hours in 2015-2016, 825 hours in 2016-2017,             1017 hours in 2017-2018 and 844 hours in 2018-2019 showed a             good behavior of the tree in all cases. No damages were             caused by ascertained temperatures as low as −12 degrees             Celsius in winter. The tree was also very resistant to             frosty springtime weather. -   Trunk:     -   -   Diameter.—Approximately 48.0 to 54.0 millimeters in diameter             when measured at a distance of approximately 20.0             centimeters above the soil level in their third growing             season (second year of production).         -   Bark texture.—Considered rough, with lenticels.         -   Lenticels.—Numerous lenticels are present. The number of             lenticels reaches 2 lenticels per cm². The lenticels range             in size from approximately 3.0 to 4.5 millimeters in width,             and about 1.5 to 2.0 millimeters in height.         -   Lenticel color.—The lenticels have a light orange color (RHS             Greyed Orange 165 B to RHS Greyed Orange 165 C).         -   Bark coloration.—The bark has a brown to grey color (RHS             Grey 201 A to RHS Grey 201 B). -   Branches:     -   -   Size.—Mature branches and current season shoots are             considered medium for the variety.         -   Diameter.—Average as compared to other nectarine varieties.             The current season shoots have a diameter from 4.0 to 6.0             millimeters, and mature branches have a diameter from 7.0 to             9.0 millimeters.         -   Surface texture.—Average, wood which is several years old             has no furrowed appearance.         -   Crotch angles.—Primary branches are considered variable, but             the crotch angles are generally 40 degrees from the             horizontal axis for current season shoots and 55 degrees             from the horizontal axis for mature branches. This             particular characteristic is not considered distinctive of             the variety, however.         -   Current season shoots.—         -   Internode length.—Generally between 15.0 and 18.0             millimeters.         -   Surface texture.—Smooth.         -   Color.—The color of new shoot tips is considered light green             (RHS Yellow Green 145 A) on lower part of new shoot tips,             whereas the upper part is darker and colored in purple (RHS             Greyed Purple 184 A to RHS Greyed Purple 184 B).         -   Mature branches.—         -   Internode length.—Generally between 18.0 and 23.0             millimeters.         -   Color of mature branches.—Brown (RHS Grey Brown N199 B to             RHS Grey Brown N199 C).         -   Surface texture.—The surface texture of mature branches is             rough, with small lenticels.         -   Lenticels.—The number of lenticels on mature branches             reaches 5 lenticels per cm². The lenticel height is             approximately 0.5 millimeter in height and the lenticel             width is approximately 0.75 millimeter. The lenticels are             stretched round in shape.         -   Lenticel color.—The lenticels on mature branches have a             beige color (RHS Greyed Orange 164 D). -   Leaves:     -   -   Size.—Considered medium for the species. The ratio leaf             length/leaf width is generally 4.11.         -   Leaf length.—The leaf length is between 135.0 and 176.0             millimeters with leaf petiole. The medium length is 155.4             millimeters.         -   Leaf width.—The leaf width is between 32.0 and 42             millimeters. The medium width is 37.8 millimeters.         -   Leaf form.—Lanceolate.         -   Leaf form (in cross section).—Concave.         -   Leaf base shape.—Acute.         -   Leaf tip form.—Acute, acuminate, short and pointed.         -   Leaf thickness.—Medium.         -   Leaf color.—         -   Upper leaf surface.—Green (RHS Yellow Green 147 A).         -   Lower surface.—A lighter green (RHS Yellow Green 147 B) than             the upper leaf surface color.         -   Leaf texture.—Both upper and lower leaf surfaces are             considered smooth and glabrous.         -   Leaf venation.—Pinnately veined.         -   Mid-vein.—         -   Color.—Light green, almost cream white (RHS Yellow Green 145             C or RHS Yellow Green 145 D). The color may evolve with             maturity.         -   Width.—Approximately 1.75 millimeters.         -   Leaf margins.—         -   Form.—Leaf margins are considered crenate (or dentate) and             slightly undulating.         -   Uniformity.—Leaves are isolated or grouped by 2 or 3. In             this last case, one leaf of normal size is found with one or             two smaller leaves (at least 50% smaller).         -   Leaf petioles.—         -   Size.—Considered medium.         -   Length.—About 10.0 to about 14.0 millimeters.         -   Diameter.—About 1.5 to 2.0 millimeters.         -   Shape.—Grooved.         -   Petioles color.—         -   Upper petiole surface.—Green (RHS Yellow Green 144 A or RHS             Yellow Green 144 B or RHS Yellow Green 143 B).         -   Lower surface.—Light green (RHS Yellow Green 145 A or RHS             Yellow Green 145 B or RHS Yellow Green 144 B).         -   Leaf glands.—         -   Size.—Considered medium. Their length is about 1.5             millimeters and their width is about 1.0 millimeter.         -   Number.—Generally 2 glands per leaf, sometimes 3.         -   Type.—Reniform.         -   Margins.—Smooth and regular.         -   Position.—Alternate on the upper part of petiole.         -   Color.—On young leaves, the leaf gland color is light green             (RHS Green 145 B). On older leaves, leaf glands color is             considered dark brown (RHS Grey Brown 199 A or RHS Grey             Brown 199 B or RHS Brown 200 A).         -   Leaf stipules.—         -   Generally.—No leaf stipules were observed. But as seen in             the characteristic relative to the leaves uniformity, it is             possible to find leaves by groups of 2 or 3, with a             normal-size leaf and smaller ones. -   Flowers:     -   -   Flower buds.—         -   Generally.—At pre-floral stage of development, the floral             buds are round in form with a round tip. Their form is             evolving until blooming, with variables dimensions. Just             before blooming, floral buds are approximately 9.0 to 11.0             millimeters wide and approximately 14.0 to 19.0 millimeters             long. The distribution of the flower buds is homogeneous on             trees.         -   Color.—This characteristic is dependent upon the proximity             to bloom. At pre-floral stage of development (stage A), the             bottom of the flower buds, or calyx, or flower receptacle,             is of purple color at the outer surface of the calyx (RHS             Greyed Purple 187 A or RHS Greyed Purple 187 B or RHS Greyed             Purple 183 A). The inner surface of the calyx is considered             orange yellow (RHS Greyed Orange 163 A). Above the calyx,             the corolla, formed by the petals, is generally of pink             color (RHS Red 55 C or RHS Red Purple 65 B) on both faces.             Petal color shows an evolution until the end of flowering.         -   Hardiness.—The buds are considered hardy under typical             central Pyrénées-Orientales departement climatic conditions.             No winter injury was noted during the last several years of             evaluation in the central Pyrénées-Orientales departement,             with winter temperatures as low as −10 degrees Celsius in             January. The current variety has not been intentionally             subjected to drought or heat stress, but the variety showed             a very good resistance in orchard to temperatures up to 42             degrees Celsius with an average temperature between 28 and             30 degrees Celsius during 3 weeks in summer.         -   Date of bloom.—The blooming time generally begins             mid-February or at the end of February or early in March.             The first bloom was observed on Feb. 21, 2016.         -   Blooming time.—Considered medium in relative comparison to             other commercial nectarine cultivars grown in the             Pyrénées-Orientales departement, France. The date of full             bloom is observed generally at the middle of the blooming             period. The date of bloom varies slightly with climatic             conditions and cultural practices. Thus, the full bloom was             observed in 2016, from February 21^(st) until March 4^(th),             then from February 26^(th) until Mar. 7, 2017, then from             February 15^(th) until Mar. 1, 2018, and then from February             28^(th) until Mar. 3, 2019.         -   Duration of bloom.—Medium, approximately between 4 to 15             days. This characteristic varies slightly with the             prevailing climatic conditions.         -   Flower type.—The variety is considered to have a showy             (rosette) type flower.

No apparent callousing or stitching exists along the             suture line. Not pointed.         -   Color.—When the suture is present, it has generally a             similar color to the whole fruit color, a luminous purple             red (RHS Greyed Purple 187 A or RHS Greyed Purple 187 B).         -   Base.—         -   Mucron.—Absent.         -   Closing of the pistil cavity.—Very good.         -   Ventral surface.—         -   Form.—Smooth.         -   Apex.—Slightly depressed.         -   Base.—Semi-flared, shallow.         -   Stem cavity.—Average depth of the stem cavity is considered             small, about 8.0 to 13.0 millimeters. Average width is about             14.0 to 18.0 millimeters.         -   Fruit skin.—         -   Thickness.—Considered medium thick and strong, and the             adherence of skin to flesh is strong to medium, depending on             the fruit maturity.         -   Texture.—Smooth and glabrous, without any pubescence.         -   Taste.—Semi-sweet.         -   Tendency to crack.—None observed.         -   Color.—         -   Blush color.—This blush color is a luminous purple red (RHS             Greyed Purple 187 A or RHS Greyed Purple 187 B). The purple             red blush covers 85 to 95% of the fruit skin surface, on a             pink red to washed red background (RHS Greyed Red 180 B or             RHS Greyed Red 79 A) covering between 5% and 15% of the             fruit skin surface. Sometimes, the purple red blush covers             100% of the fruit skin surface. The percentage of the blush             on the fruit skin surface can vary and is generally             dependent upon the prevailing conditions under which the             fruit was grown.         -   Ground color.—The ground color covers usually between 5% and             15% of the fruit skin surface, and is considered pink red or             washed red (RHS Greyed Red 180 B or RHS Greyed Red 79 A).         -   Lenticels.—None.         -   Fruit stem.—Medium in length, approximately 6.0 to 9.0             millimeters.         -   Diameter.—Approximately 4.0 to 5.0 millimeters.         -   Color.—Pale green (RHS Yellow Green 145 A).         -   Flesh.—         -   Ripens.—Very homogenously, slowly.

This characteristic varies slightly with the number of fruit             per tree; prevailing cultural practices; and the surrounding             climatic conditions.         -   Flesh color.—White to slightly cream flesh (RHS White 155 A             or RHS White 155 D), usually with a red pigmentation into             the stone cavity and a red pigmentation in a star shape             around the stone cavity. -   Stone:     -   -   Type.—Semi-Clingstone, more or less semi-adherent depending             on the fruit maturity.         -   Size.—Considered small for the variety. The stone size             varies significantly depending upon the tree vigor, crop             load and prevailing growing conditions.         -   Length.—Approximately 14.0 to 16.0 millimeters.         -   Width.—Approximately 21.0 to 22.0 millimeters.         -   Diameter.—Approximately 18.0 to 20.0 millimeters.         -   Form.—Flattened.         -   Base.—Straight.         -   Apex.—         -   Shape.—The stone apex is flattened.         -   Stone cavity.—Considered small, with flattened form and             dimensions corresponding to the stone's dimensions.         -   Stone surface.—         -   Surface texture.—The pit is transversely furrowed on its             entire surface. Furrows are deeper and more oblate on             lateral sides.         -   Ridges.—The surface texture is generally characterized by             more prominent ridges along the ventral edges and at the             apical tip.         -   Ventral edge.—         -   Width.—Narrow, approximately 2.0 millimeters at mid-suture.         -   Dorsal edge.—         -   Shape.—Grooved.         -   Stone color.—The color of the dry stone is generally             considered orange brown (RHS Greyed Orange 165 B or RHS             Greyed Orange 165 C).         -   Tendency to split.—Splitting is absent.         -   Kernel.—         -   Size.—The kernel is considered small.         -   Shape.—Elliptic flattened, sometimes double.         -   Length.—Approximately 8.0 millimeters.         -   Width.—Approximately 9.0 millimeters.         -   Thickness.—Approximately 8.0 millimeters.         -   Pellicle.—The pellicle of the kernel has a short pubescence.         -   Color.—The kernel skin is light orange yellow colored (RHS             Green Orange 164 A). The almond, which is the seed of the             kernel, is white (RHS White 155 B). The kernel and its             embryo are mature at the time of fruit maturity.         -   Use.—The subject variety ‘CAKEDIVA’ is considered to be a             white flat nectarine tree of the late to very late season of             maturity, and which produces fruits that are considered             firm, attractively colored with a very luminous purple red.             Fruits have a semi-sweet taste and are excellent for             uncooked consumption, crunchy or melting when at full             maturity. Fruits have excellent gustative qualities. Due to             their flesh quality, firmness and density, they can also be             commercialized as 4^(th) range product (packed fruit or             fruit in bags for example). And they are also useful for             both local and very long-distance shipping.         -   Keeping quality.—Remarkable. Fruit have a slow maturation             and a long shelf life both on the tree after growth             completion and after harvesting without alteration. After             growth completion, fruits are preserved more than one week.             After harvest, fruits are well preserved more than 4 weeks             at 2.0 degree Celsius.         -   Shipping quality.—Considered very good. The fruit of the new             white flat nectarine variety showed minimal bruising of the             flesh or skin damage after being subjected to normal             harvesting and packing procedures. Its resistance to             handling during harvest and packing and its long shelf life             without alteration after harvest easily permit 3 to 4             weeks-shipping at 2 degrees Celsius.         -   Resistance to insects and disease.—No particular             susceptibilities were noted. The present variety is not very             sensitive to Monilia or rot. The pistil cavity is completely             closed, generally without any cork formation.

Although the new variety of white flat nectarine tree possesses the described characteristics when grown under the ecological conditions prevailing near Elne, Pyrénées-Orientales departement, France, it should be understood that variations of the usual magnitude and characteristics incident to changes in growing conditions, fertilization, pruning, pest control and horticultural management are to be expected. 

I claim:
 1. A new and distinct variety of white flat nectarine tree as illustrated and described, characterized by its late maturity time, its fruits with high eating quality and very long shelf life without alteration before and after harvesting, with a semi-sweet white flesh, sometimes with a red pigmentation in a star shape around the stone cavity and into the stone cavity, and an attractive luminous skin with a high to very high percentage of luminous purple red blush on skin surface, on a pink red or washed background.
